Overview
The AD7687BRMZRL7, produced by Analog Devices Inc., is a 16-bit, charge redistribution, successive approximation analog-to-digital converter (ADC). This device operates from a single power supply, VDD, ranging from 2.3 V to 5.5 V, and is designed for high-speed, low-power applications. It features a low noise, wide bandwidth, and short aperture delay track-and-hold circuit, making it suitable for various precision measurement tasks. The AD7687 is available in 10-lead MSOP and 10-lead LFCSP packages and is specified for operation from -40°C to +85°C.
